George the goldfish had a 45-minute operation to remove a life-threatening tumor at Lort Smith Animal Hospital in Melbourne, Australia, last week.
George's owners were reportedly very attached to the 10-year-old goldfish. After discovering the tumor, they opted not to put the fish down but to have him operated on.
George had to be given general anesthetic, so Dr. Tristan Rich, the veterinarian performing the operation, had George swim in a bucket of water laced with anesthetic.
When the operation was done, they put George in a bucket of normal water. He was given painkillers and antibiotics, and after a few minutes he started swimming around, good as new.
According to the hospital's Facebook page, the surgery went "swimmingly" and George has returned home. As long as George stays in good health, he's expected to live another 20 years.
